mess

this is the mess I left till I melt another alumn. wheel.

pattern rework

added 5/8 inch to housing for tapping purposes then it will be usable.

Better Core needed

got rid of moisture pockets now i have to get a finer sand for better core surface. now i have to rework pattern because i can't tap the other end of the housing.

drill bits

drill bits my brother gave me 20+ years ago. As you can tell some have gone on their seperate path.

moisture

not nearly as bad as the first one but still not usable. Let the core sit out overnight and it dryed somewhat but not enought. oh well back in the pot and keep trying.

core mold out of sand

core mold almost finished

pattern with core

fresh out of sand

back in the pot

i might have mixed to much silicone silicate in sand , moisture does this to aluminum.

shop, disorganized and a slob works in here

lathe 13" regal

lathe

mill

air cylinder

when your still a want-ta-be machinist and do lousy work you powder coat it.

cyl. heads and bases

these cylinders are for small air compressure.

one way check valves for cyl.

crap, sand to wet

vise in foam

mill vise

pyrometer

hot enought

half way there

rails ready to cast

co2 maker

this is my way of applying co2 to set sodium in sand. Lite a candle or a piece of paper in a container set lid and leave it for about 15 min it sets core to usable/

core mix

not knowing how to mix sodium silicate, i mixed it 3 parts water to 1 part sodium ,then i mixed it to sand a little dryer than green sand semed to work.

5 pointed nuts and bolts, wow
